We took DS when he was just under 4 months, our older DS was devastated to miss Star Wars Weekends, and baby was easy so we booked last minute. It was fine!! Here are my tips:
-Know where every baby center is. I spent a lot of time there.
- accept that one of you might need to miss some pool time, or night in the park, to give the baby some quality rest
-bring a really good, shady stroller and some Muslin or light cotton to drape over for more shade
- talk to your pediatrician about sunblock and fluids if it's very hot
-bring a sling or some type of baby wearing device, sometimes it was easier to carry him then have him in and out of the stroller, and a lot of restaurants/QS don't allow strollers
- make sure you utilize baby swap passes
PM me if you have questions! If I think of more I will come back. We all Survived, he took his second trip in Sept at 7 months and will go back in Feb!
